We could put the domain into the x values to get the y values (range).
y = 3(-3) - 4
y = -9 - 4
y = -13
y = 3(-1) - 4
y = -3 - 4
y = -7
y = 3(4) - 4
y = 12 - 4
y = 8
Answer:
m or slope=3/2
Step-by-step explanation:
The pattern is multiply by -4. So to find the next number. Multiply the previous one by -4.
5/7m=-55
1.) First of all they are multiplying so you do the opposite. In this case you divide 5/7 by both sides.
-55divided 5/7
Changes to
-55/1 x 7/5. See if you can cross cancel in this case you can. The -55 changes to a -11 and the 5 changes into a 1
Reminder: Remember when you divided by fractions you change the sign to a multiplication sign and then flip the next fraction over.
2.) After dividing you should get -77/1 or if you didn't cross cancel then you would get -385/5.
3.) If you get -385/5 then you would have to do 385 divided 5 and you would get -77.
4.) Checking your answer is 5/7•-77=-55.
5/7•-77 changes to 5/7•-77/1 and you can cross cancel it where the -77 changes to a -11 and 7 changes to a 1.
5.) You should get -55. If you didn't cross cancel then you would have gotten -385/77
6.) If got -385/77 then you would do -385 divided by 77. Your then should get -55.
7.) Look to see if the answer you got when you checked matches the answer in the problem. -55=-55
8.) Your answer is -77
